Fast forwarding is slow on the Steam Deck

Some emulators run slow when I got my Steam Deck docked to a 4k, 8k or above resolution monitor.

The Steam Deck does not have the power to play all the games in those high resolutions with a stable framerate. What you could do is go into desktop mode while docked and lower the resolution of the display to 1080p or 720p then return to gamemode.

I am having problems with my SD card on my Steam Deck: It cannot be found since SteamOS 3.5

Some users of SteamOS have had a problem since the upgrade to SteamOS 3.5 by Valve.

It changed how the SD cards were mounted and gave them a new path and in some cases, this broke the auto-mounting on boot. There are several issues on Valves SteamOS github mentioning this. This does not only affect RetroDECK but also all games and files you could have on the SD card.

The solution some found was either to reset the entire Steam Deck and reformat the card or to go into Desktop Mode on each boot and click on the card from the GUI to make sure it is mounted. But these issues might be fixed in an upcoming update to SteamOS.

NOTE: Valve does not recommend users to fix it by editing fstab or using something link Gnome Disks or KDE Partition Manager to do so. This could break other things.
